http://www.prolabinc.com/instructions/oneflush.html It states here that it has 9.7 billion per gram in the one-flush not 1/2 oz or packet. The packets are half oz. (135.8 cfu per packet) Then that would make it cheaper right? How many one-flush products are out there? This link is to the one I purchased. The bacta clean states 10 Billion per gram with bulk discount. The one flush states 9.7 billion per gram. The one flush is 25% cheaper before they give a bulk loose powder discount. Please show me what else I am missing, because I still cannot find it cheaper to use bacta clean over one flush.
